MPTP is used to model Parkinsonās disease. It turns into MPP+ and leads to the death of dopaminergic neurons. How was this figured out?
MPPP was an opioid synthesized in 1947. Due to difficulty acquiring heroin at the time, Barry Kidston read the MPPP paper in 1976 and tried to synthesize it, but it had MPTP impurity š±
He presented with Parkinsonian symptoms, was treated, but died of an overdose. Autopsy revealed loss of SN DA neurons. NIMH found MPTP in his lab.

ACE-inhibitors are a type of drug used to treat #hypertension. They prevent angiotensin converting enzyme (ACE) from turning angiotensin I to II, BUT they can trigger the cough reflex!
If youāre having chronic cough issues with an ACE-inhibitor (drug name usually ending in -il), talk to your doctor about other options š«
Good morning, and happy #PharmPhriday!
I regularly revisit this piece on #tetanus in an unvaccinated child. It is short, fascinating, heartbreaking, and incredibly frustrating story: https://www.cdc.gov/mmwr/volumes/68/wr/mm6809a3.htm

Happy #PharmPhriday! A question I get a lot is āwhatās a #biosimilar?ā Well, itās like a #generic but for #biologics
Because a biologic is made from something living, you canāt exactly copy the drug recipe like you can with generics. There are also some differences in testing.
A biosimilar has no clinically meaningful differences from an existing FDA-approved biologic.
A generic drug demonstrates bioequivalence to an existing FDA-approved drug.

#Hormones can be confusing, so letās break down some of their functions, starting with progesterone. One important role is maintaining a pregnancy (hence why #mifepristone, a progesterone blocker, is an #abortion drug).
#Progesterone can be administered intramuscularly (in oil, PIO) or vaginally; oral has been shown to be less effective.
If you donāt want a daily šš through 1st trimester, talk to your doc about vaginal progesterone! #OBGynodon #Fertility #Infertility #IVF

Happy #PharmPhriday! With the š„¶ season still hitting, you might be prescribed benzonatate (Tessalon) pearls. This drug works on vagal afferent fibers and stretch receptors to reduce the cough reflex.
Accidental ingestion by children under 10, even 1-2 capsules, can lead to overdose and death. Overdose symptoms can have a rapid onset, within 15-20min of ingestion.
I keep track of how many Iāve taken by using a tally on the bottle to know if any are missing.

Itās #PharmPhriday! We have personally been affected by the injectable lidocaine shortage, so today will be about lidocaine! Some cells signal via action potential. When thereās sufficient stimulus (like pain!), sodium enters the cell, potassium (also positively charged) exits, then the cell membrane returns to baseline āresting potentialā.
Sodium enters through a sodium channel, and what does lidocaine do? Block sodium channels! No sodium entry, no action potential, no pain signal.
Happy #PharmPhriday! We joke about the āDrā in āDr Pepperā, but did you know it was created by #pharmacist Charles Alderton in the 1880s? Dr. Pepper (period dropped in the 1950s) advertised as being able to aid digestion and restore vim, vigor, and vitality āØ
While searching #vintage ads, I saw a few saying to drink it at 10, 2, and 4, and even old bottles with the numbers on the logo. This is from an old slogan contest, after showing those times of day are associated with dips in energy.

Itās #PharmPhriday! Due to the #Speaker #Fiasco in the #House, Iāll share some #etymology.
Did you know both candidiasis (yeast infection) and candidate stem from the Latin candidus meaning āshining whiteā?
In ancient #Rome, political candidates would wear super white togas while campaigning and were known as candidati or āwhitened menā, presumably to signify their pure intentions.

Unfortunately, there was not much that could be done about it, and the company got away with some fines for minor things like calling the drug an āelixirā but not containing alcohol.
This tragedy resulted in the 1938 Food, Drug, and Cosmetic Act requiring safety and quality standards for food, drugs, medical devices, and cosmetics.
But notice I did not say safety *and* efficacyā¦stay tuned for next weekās #PharmPhriday!
